MACHINE FOR MAKING ROLL-PACKING.

Application filed January 2, 1820.

To all whom it may concern Be it known that 1, WILLIAM J. KENT, a citizen of the United States, residing in the borough of Brooklyn, city-of New York, county of Kings, and State of New York, have invented certain new and useful Improvements in Machines for Making Roll- Packing, of which the following is a full, clear, and exact description.

This invention relates to a machine for making rolled packing, and it may be used for rolling packing either with or without a core.

Machines at present in use for this purpose consist of a revolving drum having a segmental apron spaced therefrom, and in operation a core is placed at the edge of a strip of packing, the packing given a number of rolls around the core and the roll then inserted between the apron and drum, the rotation of the drum with respect to the apron serving to finish the rolling of the packing. In the case of a coreless packing the operation is similar except that the packing is rolled up directly upon itself. Vfhen the roll is inserted between the drum and apron it is necessary for the operatives to pass along the front of the drum and press in the roll throughout its length between the apron and drum with an implement. As the success of this operation depends entirely upon the skill and care of the operator the quality of the packing varies considerably due to the uneven insertion of the roll, the finished product being hard where pushed in too far and soft where not pushed in far enough. In addition the faces of the drum and apron are both polished and be come very smooth from use and as a result the friction cloth is frequently not evenly gripped causing the cloth to kink, thereby producing a defective roll of packing. The

prior machines are also very noisy in opera-- tion, as the discharge-end of the apron is provided with stops adapted to contact with the frame of the machine and prevent theapron from striking the drum as roll of packing is discharged from between the drum and apron. This constant pounding of the stop against the frame causes considerable noise during operation.

An object of the present invention is to provide a machine capable of producing a larger quantity of a more uniformly rolled packing.

Specification of Letters Patent.

Patented Dec. 14, 1920.

Serial no. 349,124.

Another object is to provide means for evenly introducing the packing or the core and packing to the machine.

further object is to provide means for giving the core and packing an initial partial roll as they re inserted in the machine, which means is adjustable for different thicknesses of core and packing.

still further object is to provide a machine operating with greater quietness.

A still further object is to provide an improved means for supporting and adjusting the apron of the machine.

In the drawings:

Figure 1 is a front elevation of the machine with its operating table removed.

Fig. 2 is a vertical section through the machine.

Fig. 8 is a perspective showing a core with a packing strip partially rolled thereon.

Fig. 4 is a perspective of a sheet of packing, showing the manner of starting the roll when a core is not used.

Referring to the drawings, the numeral 1 is applied to the side frames of the machine. Journaled in the frames is a shaft 2 carrying the drum 3, a pulley 4: being secured to the end of the shaft and driven by a belt from a desired source of power. It is obvious, however, that the drum can be rotated by any suitable means. Extending between the side frames at their tops is a shaft 5 having eccentric portions 6 journaled in spaced bearing brackets 6. Outside the side frames the shaft carries disks 7 each having a series of apertures 8 therein, which apertures by the rotation of the disks may be in turn brought in register with openings 9 in the side frames, pins being inserted in the openings 9 and alined apertures 8 to secure the disks in adjusted position. Beyond the disks 7 the shaft is provided with squared ends 10 by which it may be readily turned. A series of links 11 are hung upon the shaft 5 by means of eyes 12 at their upper ends, the links being extensible by means of turn buckles 13 disposed at their middle portions. At the lower end of each link is an eye 14 adapted to pass between apertured brackets 15, the brackets being secured to the eyes by bolts 16 passing through the apertures in the brackets and the eyes and held in place by nuts 17 Secured to the brackets 15 is a curved segmental apron 18 having upwardly turned sides 19. Weights may be disposed in' this apron between the upturned sides 19 to secure the desired pressure of the apron upon the roll. The inner surface of the apron 18 is serrated at its forward end as shown at 20 for a purpose to later de-.

scribed. Chains 21, in the present instance two in number, are secured to the bottom or rear end of the apron, the upper ends of the chains being secured to threaded pins 22 passing through the upper part of the frame, which pins are held in adjusted position therein by means of the nuts 23 and 24:. It is obvious that any desired number of links 11 and chains 21 may be used. A crossbar 25 extends between the side frames at the front of the machine and secured to this crossbar is a series of apertured supporting lugs 26. An eccentric bolt 27 is secured in each apertured lug by nuts 27, by loosening which it may be adjusted. Pivotally suspended 011 each bolt is an angled piece 28, the several angled pieces being connected by a bar 29 serving as a handle and also as a brace. Secured to the forward ends of the angled pieces 28 is an angled plate or pusher 30, the rearwardly directed edge of which is rounded as shown at 31. The opposite ends of the angled pieces carry counter weights 32. Also secured to the crossbar 25 is a curved core table or shelf 33 in which the cores when used are placed for ready access by the operator. At the front of the drum a table 34 is disposed upon which the strip of packing may be placed and given its initial roll, either with or without a core, before insertion in the machine. At the rear of the machine an inclined surface 35 is disposed for carrying away the finished rolls of packing.

In operation a core 36 is disposed at the edge of a strip of packing 37 and if desired the packing is given a partial roll around the core as shown in Fig. 3, although this is not essential. The core and packing strip are then inserted between the apron and drum, and the operative by swinging the plate or pusher 3O downwardly by the handle 29 causes the rounded edge 31 of the plate to strike the core 36 slightly below its middle portion. Upon pushing the plate 30 inwardly the core and packing areevenly inserted between the drum and apron throughout their length, and at the same time the edge 31 causes the core to be rotated by pressure on its bottom portion while the upper portion or the edge of the packing is frictionally held by the serrated surface 20. As it. is necessary, in order to give the core and packing strip this partial rotation, that the plate 30 strike below the central portion of the core 36, or in the case of a coreless roll below the center of the roll, it is evident that the plate must be adjusted for different diameters of core and thicknesses of acking. As the machine is run for long perio 's on the same size of core and packing this adjustment need not frequently be made. However when necessary it is accomplished by loosening the nuts 27 and rotating the eccentric bolts 27 thereby raising or lowering the pivotal point of the plate 30, the nuts 27 being tightened again when the desired adjustment has been made. The upper or forward end of the apron can also be adjusted to vary its spacing from the drum in accordance with different sizes of cores or packing. This can be accomplished by means of the turn buckles 13 or by rotation of the shaft 5, the shaft being retained in adjusted position by means of pins inserted through the apertures 9 in the frame and 8 in the disk 7, as before stated. The rear end of the apron may be adjusted by means of the nuts 23 and 24 on the pins 22 carrying the chains 21. It will be noted that by means of the chains 21 the use of stops on the apron 18 contacting with the frame is obviated, thus doing away with the noise caused by the contact of the stops with the frame.

If coreless packing is to be made, a sheet of the packing material is manually rolled up on itself at one edge as shown in Fig. 4 and the rolled up portion evenly introduced between the drum and apron by means of the plate 30, and the rolling is then completed by the machine in a manner similar to that described for the rolling of the core packing.

As shown in Figs. 1 and 2 the engaging edge 31 of the plate or pusher 30 is continuous, but this is not essential and the edge may be serrated or cut away, the only requisite being that the packing roll be engaged from end to end at points which are closely enough spaced to cause the even insert-ion of the roll at all points in its length.

By the use of my improved machine the time required for producing a roll of packing is greatly reduced, and owing to the even insertion in the machine a roll of uniform hardness throughout results.
